BEST-III-Ecosystem-Profile-Aruba-DRAFT.Pdf BEST%III%'%Working%document% ! Remark: This document gathers information from the list of references previously validated for the island. It is a working document that will be implemented following your comments and corrections. It will be used as a guide during the consultation process that will involve local governments, institutions and organizations. The objectives are to identify and map Key Biodiversity Areas (KBAs) in order to define conservation outcomes. KBAs are defined at 3 ecological levels: (1) species, including: globally threatened species, restricted-range species, and species gathering in important number during their life cycle; (2) sites: habitats that are home to the species previously identified; habitats and ecosystems that play important ecological processes and contribute to the persistence of biodiversity ; (3) ecological corridors: inter-connected landscapes of sites. Regarding the information and references cited hereafter, a list of "potential KBAs" is proposed in App.2. This is a working process that will be validated through the consultation of local actors. Ecosystem profile Draft - Aruba IBAs, RAMSAR site and Parke Nacional Arikok in Aruba Policy and Socioeconomic context ! Political Status - Aruba lies off the north-west coast of Venezuela and is the westernmost of the 3 Dutch islands (c.80km from Curacao). Curacao, Aruba and Bonaire (also called the ABC islands) form the Leeward Islands of the Kingdom of the Netherlands. Aruba is the nearest Dutch island to mainland Venezuela and is located 27km north from Paraguaná peninsula. The maximum depth between Aruba and the Venezuelan coast does not exceed 135 m, whereas BC islands are separated from South American mainland by a deep water trench (c. 1000m). - Since January 1986, Aruba became an independent country within the Kingdom of the Netherlands. St Maarten and Curaçao followed in October 10th 2010. This island is a European Oversea Country of the Kingdom of the Netherlands. ! Demographic Trends and Socio-economic context (Central Bureau of Statistics) - Area: 193 km² (Mount Jamanota, 188m) - EEZ: 25,287 km², EEZ of the ABC Islands: 68,873 km² - Population (2014): 107,394 inhabitants, density: 556 inhabitants /km² - GDP (US$/ inhabitant): 25,300 (2011) - Aruba is one of the richest countries in the Caribbean. 1! ! BEST%III%'%Working%document% ! - Main economic activities: oil refining and trans-shipment facilities; off-shore financial services; tourism, with associated services and construction industries. Protected and/or managed areas (References: DCNA 2012a) ! List of protected areas - Parke Nacional Arikok (created in 2000 over 3,400 ha) is managed by Fundacion Parke Nacional Arikok. This land area covers about 18% of the island, includes Mount Jamanota (highest peak, 188m) and significant areas of cactus scrub. There is 15 privately owned plots of land within the Park. - In Aruba’s Zoning policy document of 2009 four marine areas were indicated to be managed as marine protected areas (Ruimtelijk Ontwikkelingsplan Aruba - Planbeschrijving 2009). These 4 marine areas gather important coral reefs and seagrass beds: coastal and marine area contiguous to Parke Nacional Arikok, coral reefs close to Oranjestad, "Eastern Cape" Sero Colorado and Mangel Halto-Isla di Oro. For now, there is no marine park officially created. - The Aruba Marine Park Foundation, a citizen organization, has been created in 2010 to ensure the sustainable use of marine resources and to strengthen the protection of the marine environment and wildlife through the creation of a marine park. For now, this local NGO has not a specified area to manage according to the Nature conservation ordinancy. - Aruba’s Zoning policy mapped the eastern side of the island as natural contiguous areas ("natuurgebied", Ruimtelijk Ontwikkelingsplan Aruba - Planbeschrijving 2009).

  • Crotalus Unicolor (Van Lidt De Jeude), Aruba Island Rattlesnake
    4 I Litteratura Serpentium, 1993, Vol. 13, No. 1 CROTALUS UNICOLOR (VAN LIDT DE JEUDE), ARUBA ISLAND RATTLESNAKE By: Pete Strimple, 5310 Sultana Drive, Cincinnatti, Ohio 45238, U.S.A. Contents: Historical - Taxonomic status - Phylogeny - Description - Scalation - Size-Longevity - Range - Habitat - Food - Habits-Behavior - Venom - Reproduction - Status -Acknowledgements - References. * * * HISTORICAL The Aruba Island rattlesnake was first descnbed in 1887 by Van Lidt de Jeude as Crotalus horridus variation unicolor. The type locality was given as 'Aruba,' referring to Aruba Island, Netherlands Antilles (also called Dutch West Indies). Van Lidt de Jeude's original description was actually based on 4 specimens, two of which were preserved specimens and two of which were alive at that time but are now considered cotypes (Brongersma, 1940). The specific name 'unicolor' is derived from two Latin words; unus (one) and color (color) (Brown, 1978). This name refers to the faded and almost uniform color and pattern of adult specimens. TAXONOMIC STATUS Even today, there is still controversy over whether the Aruba Island rattlesnake is a distinct species, or simply a subspecies of Crotalus durissus. Since a majority of herpetologists seem to regard this rattlesnake as a distinct species, as does this writer, I have elected to give this snake full species status in this article. As I mentioned in my article on Crotalus durissus vegrandis, the entire 'durissus' group of rattlesnakes is in need of revision (Strimple, 1987). It is hoped that the forthcoming publication by Campbell & Lamar (in press) will provide information which will clarify the taxonomy of these rattlesnakes as a group, and Crotalus unicolor in particular.

Marschang Institut für Umwelt und Tierhygiene, University of Hohenheim, Garbenstr. 30, 70599 Stuttgart, Germany; E-Mail: [email protected]; Tel.: +49-711-459-22468; Fax: +49-711-459-22431 Received: 2 September 2011; in revised form: 19 October 2011 / Accepted: 21 October 2011 / Published: 1 November 2011 Abstract: A large number of viruses have been described in many different reptiles. These viruses include arboviruses that primarily infect mammals or birds as well as viruses that are specific for reptiles. Interest in arboviruses infecting reptiles has mainly focused on the role reptiles may play in the epidemiology of these viruses, especially over winter. Interest in reptile specific viruses has concentrated on both their importance for reptile medicine as well as virus taxonomy and evolution. The impact of many viral infections on reptile health is not known. Koch’s postulates have only been fulfilled for a limited number of reptilian viruses. As diagnostic testing becomes more sensitive, multiple infections with various viruses and other infectious agents are also being detected. In most cases the interactions between these different agents are not known. This review provides an update on viruses described in reptiles, the animal species in which they have been detected, and what is known about their taxonomic positions. Keywords: reptile; taxonomy; iridovirus; herpesvirus; adenovirus; paramyxovirus 1. Introduction Reptile virology is a relatively young field that has undergone rapid development over the past few decades.

  • Bayesian Mixed Models and the Phylogeny of Pitvipers (Viperidae: Serpentes)
    Molecular Phylogenetics and Evolution 39 (2006) 91–110 www.elsevier.com/locate/ympev Bayesian mixed models and the phylogeny of pitvipers (Viperidae: Serpentes) Todd A. Castoe, Christopher L. Parkinson ¤ Department of Biology, University of Central Florida, 4000 Central Florida Blvd., Orlando, FL 32816-2368, USA Received 6 June 2005; revised 2 December 2005; accepted 26 December 2005 Abstract The subfamily Crotalinae (pitvipers) contains over 190 species of venomous snakes distributed in both the Old and New World. We incorporated an extensive sampling of taxa (including 28 of 29 genera), and sequences of four mitochondrial gene fragments (2.3 kb) per individual, to estimate the phylogeny of pitvipers based on maximum parsimony and Bayesian phylogenetic methods. Our Bayesian anal- yses incorporated complex mixed models of nucleotide evolution that allocated independent models to various partitions of the dataset within combined analyses. We compared results of unpartitioned versus partitioned Bayesian analyses to investigate how much unparti- tioned (versus partitioned) models were forced to compromise estimates of model parameters, and whether complex models substantially alter phylogenetic conclusions to the extent that they appear to extract more phylogenetic signal than simple models. Our results indicate that complex models do extract more phylogenetic signal from the data. We also address how diVerences in phylogenetic results (e.g., bipartition posterior probabilities) obtained from simple versus complex models may be interpreted in terms of relative credibility. Our estimates of pitviper phylogeny suggest that nearly all recently proposed generic reallocations appear valid, although certain Old and New World genera (Ovophis, Trimeresurus, and Bothrops) remain poly- or paraphyletic and require further taxonomic revision.

Although four species (C. culminatus, C. durissus, C. simus and C. tzabcan) are currently recognized, species limits remain to be tested. Previous genetic studies suggest that C. durissus and C. simus may be paraphyletic and that at least one cryptic species may be present. We analyzed 2596 bp of DNA sequence data from three mitochondrial and one nuclear gene to infer phylogenetic relationships in the Neotropical rattlesnakes.
